Hope this helps:

class Channel < Struct.new(:name, :id)
   def self.parse(io)
     io.inject(Array.new) do |channels, line|
       if line =~ /\bChannel\b/
         channels << new
       elsif not channels.empty? and line =~ /\A\s+(name|id):\s+(.+)/
         channels.last.send("#{$1}=", $2)
       end
       channels
     end
   end
end

if __FILE__ == $PROGRAM_NAME
   p Channel.parse(DATA)
end

__END__
- Channel
   name: foo
   id: 3
- Channel
   name: bar
   id: 4
